SPRAY-NOZZLE.

Specification of Letters Patent.

Eateuted April 2, 1907.

Application filed April 10, 1906. Serial No. 310 901.

T aZZ whom it may concern:

Be it known that I, ARTHUR B. HULL, a citizen of the United States, residing at Gasport, in the county of Niagara and State of New York, have invented a new and useful Spray-Nozzle, of which the following is a specification.

In nozzles employed in spraying insecticides and the like considerable difficulty has been experienced in securing a comparatively great body of mist or spray from a single nozzle, and it is now the usual custom to employ a cluster of nozzles. Because of the supports and conducting-tubes therefor these are troublesome to use among the branches, and, besides, the nozzles being comparatively small are liable to become choked or clogged by small particles of undissolved insecticides, involving delay and consequent loss of time in taking them apart to cleanse the same.

The principal object of the present invention is to provide a novel and simple nozzle from which a great body of spray is thrown in a gyratory path and with comparatively great penetrating power, said nozzle being so constructed that it is not liable to become clogged, but so arranged that it can be easily taken apart for the purpose of cleansing it.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the nozzle. Fig. 2 is a sectional view of the same. Fig. 3 is a top plan view of the nozzle with the cap removed. Fig. 4 is a perspective view of the deflecting-plug.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated a cylindrical casing 5 is employed having an interior chamber 6 and a nipple 7 projecting from one end and having a threaded bore 8, that communicates with the chamber 6 and is of less diameter than the same. The rear end of the casing is provided with an annular outstanding drip-stop flange 9, while the front end of said casing is open and is exteriorly threaded. The front portion of the chamber is counterbored, thereby forming an annular shoulder 10 between the ends of said chamber.

A deflecting-plug 11 is fitted in the chamber and bears at its inner end against the shoulder. Said plug-is provided with a helical liquidconducting channel 12 in its periphery, which channel thus communicates with the inner portion of the chamber 6' and opens through the outer end of the casing. A cap 13 is threaded upon the outer end of the casing and covers the plug, being provided in its front wall with a central opening 141. A plate or disk 15, preferably of hardened steel, is located inside the cap and has a central circular orifice 16, that is disposed centrally of the opening 14. A packingwasher 17 is interposed between the peripheral portion of the disk 15 and the end of the casing 5, said washer extending over the margin of the outer end of the plug 11 and closing the circular joint between said plug and the casing.

It will be observed by reference to Fig. 2 that the outer end of the plug 11 is flush with the outer end of the casing 5, and that consequently when the cap is screwed home the packing not only clamps the plate 15 in position and prevents leakage about the same and through the screw-threaded joint between the cap and casing, but that it also bears against the plug 11 and holds the same to its seat or against the shoulder 10, thereby securely maintaining the plug against rotation. Moreover, it will be observed that the packing-ring spaces the plate 1.5 and front wall of the cap from the front end of the plug, forming an interior chamber, also that the ring terminates short of the inner side of the helical channel, so that said channel communicates with the chamber. As a result if liquid under pressure is introduced into the chamber 6 through the inlet 8. This liquid escapes through the helical channel 12 and is given a rotary motion in the interior chamber, finally discharging through the orifice 16 in the form of a cone-shaped gyratorybody of fine mist or spray of great penetrating power. Any drip which may take place is stopped. by the flange 9 and is thus prevented from traveling down the conducting-pipe.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be under stood that various changes in the size, shape, proportion, and minor details of construction may be resorted. to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

In a spray-nozzle, the combination with a casing, of a plug fitting in the casing and having its outer end substantially flush with one end. of said casing, said plug having a helical conducting-channel in one side, a cap detachably mounted on the end of the casing" having the plug, and a packing-ring interposed between the front Wall of the cap and the adjacent ends of the casing and plug, said ring engaging both the casing and plug e ieees and spacing the front Wall of the cap therefrom. to provide an interior cl'iamber inclosed by the ring, said r ng furthermore terminating short of the inner side of the channel oi l'llO plug so hat said channel communicates with the interior chamber and the cap having an outlet communication with said interior chamber.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses. i
